I BOAT.

srmmmm amm part of Letters Patent Ne. 514,824, dated February 13,1894.

' Application filed March 6, 1893. $erial No. 464,711. (No model.)

Be it known that 'I, ALFREDO DCos'r GOMEZ, of Bucaramanga, Colombia, South America, have invented a new and useful Improvement in Boats, of' which the following is a full, clear, and exact description.

bining strength and lightness with shallow-- ness of draft.

It is a further object of the invention to so construct the boat that it may be floated in water of exceedingly shallow depth and wherein the boat may carry machinery to propel it, and may likewise carry freight and passengers.

r The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters and figures of reference indicate corresponding parts in all the views.

Figure 1 is a horizontal section through the upper structure of the boat, taken practically on the line 11 of Fig. 3. Fig. 2 is a plan View of the lower structure or hull of the vessel in section on the line 22 of Fig. 3. Fig.

3 is a transverse section taken essentially on the line 3--3 of Fig. 1. Fig. 4 is a side elevation of a slightly modified form of the boat; and Fig. 5 is a horizontal section taken essentially on the line 5-5 of Fig. 4.

In carrying out the invention a number of floats A, is employed to form the foundation, or more properly speaking, to constitute the hull of the vessel. The floats are made in the shape of hollow cylinders, being formed conical or pointed at one end, as shown at 10 in the drawings, and flat at the opposite end as indicated at 11. The cylinders may be made of any approved material; preferably, how ever, a light metal is employed for that purpose. The pointed ends of the floats are made to face what is intended to be the bow of the vessel, and the floats are arranged in any desired number of series B, three series being shown in the drawings, and each series consists of any desired number of floats arranged side by side. Those at the bow are arranged so that their outer ends form somewhat of a semi-circle, but the bow formation may be rendered more or less sharp, as in practice may be found desirable, while the outer ends of the last series, which arethe flat J ends of the floats, are arranged in a straight line, as best shown in Figs. 1 and 2. The outer floats of each series are preferably stepped back or carried rearward beyond the intermediate floats of a series in order that at the stern of the hull the outer floats will project rearwardly and form supports for rudders, as it is intended that two rudders shall be used, one attached to the hull at each rear extension 12, thereof, although but a single rudder may be employed if in practice it is found desirable; and the rudder or rudders maybe stepped in any approved manner. Each float has secured upon its upper face, longitudinally thereof, a beam 13, and the floats of each series are connected by transverse beams 14, crossing all the floats in a series, the cross bars 14, being attached to the float beams 13 by means of bolts, rivets or equivalent fastening devices. The various cross beams 14 of the several series are connected by longitudinal deck beams 15, as shown in Fig.2, and upon these beams the deck 16, is erected and supported. Preferably at the margin of the deck pillars or posts 17, are erected, supporting a roof or canopy 18, while a railing 19, may be placed between the several posts, as shown in Fig. 3; and if a deck house 20, is employed, the structure may be made in any manner that fancy may dictate, and may rest upon the deck at the forward central portion thereof, while in the rear a space 21, is provided to receive machinery when the vessel is to be propelled by steam.

In Figs. 4and5 I have illustrated a slightly modified form in the construction of the boat, in which it will be observed that at the central portion of the boat no floats are located. The floats, however, extend along the side in ICC series, as described in connection with the form above spoken of, and the floats are arranged in a continuous transverse series at the bow. The central portion of the hull is formed by carrying the deck house downward to practically fill the space between the side and the bow floats, the lower portion of the deck house being provided with a keel 22, and the lower portion of the keel is in the same plane as the lower faces of the floats. The deck house is continued upward as a structure preferably for either the entire length or a portion of the length of its hull section. In the drawings, however, the deck house 23, is made to extend from the forward portion of its hull section to a point abaft the center, the remaining or rear section 24: of the inclosed hull being adapted to receive machinery. Thusitwill be observed thata hold 25, is provided in this form of boat, and the transverse beams 14, utilized to tie the floats of a series together, are passed through the hull section of the deck house, stiflening the entire structure. The deck 16, is constructed around the deck house and around the portion 24 of its hullsection, and the said deck house may be provided with asuitable flooring, if desired, and also with a roof 25, as shown in Fig. 5. In this form of boatposts or stanchions 26, are erected along the margin of the deck, the posts or stanchionsbeingconnected by railings 27 of any approved construction, while the stanchions are adapted primarily to support the main roof of the boat, designated as 28, which extends from side to side and from bow to stern.

It will be observed that a vessel constructed in the manner above described, will be enabled to float in extremely shallow water, and to successfully navigate streams in Which the current is very strong, and in which the water is but of little depth above a rocky bottom.

Having thus described my invention, I claim as new and desire to secure by Letters Patent-- 1. In a boat, a hull formed of a number of series of hollow cylinders, each cylinder having one end pointed, the front or how series being arranged so that their pointed ends will form substantially a semi-circle, and the outer cylinders of the rear orstern series being projected rearward beyond the intermediate cylinders of the series, as specified.

provided with longitudinal beams secured upon their upper faces, transverse beams secured to the longitudinal beams, and longitudinal deck beams secured to the transverse beams, substantially as described.

4. A boat, comprising a hull formed of 1101- low cylinders having one end pointed and arranged in a number of series, the front or bow series being arranged so that their pointed ends will form somewhat of a semi-circle, a deck supported upon the cylinders and a deck house projecting above the deck, substantially as described.

5. In the construction of a boat, ahull the same consisting of a bow section constructed of a series of hollow floats having pointed forward ends, and side sections constructed in like manner as the forward section, cross bars connecting the transverse series of floats,tiebeams connecting the cross bars, and a well section located between the bow and side floats, the well section extending downward flush with the under faces of the floats, the lower portion of the well acting as a keel and providing a hold for the hull, as and for the purpose specified.
